JST connector – female


If you’ve connected a lipoly battery in your robot or other device, odds are that you’ve seen a JST female two pin connector attached to your battery.  Ours are high quality, high strand count silicon wire.  This gives a higher amp throughput vs the standard wire of the same diameter. Connectors are plated for higher current handling and reduced intermittency due to oxidation. Great for a power disconnect in a low current system, or as a general connector in smaller bots. JST’s are used on out Galaxy Lipoly battery packs.
